Abstract

PURPOSE:To execute some displaying to a displaying part and to delete an unnatural feeling by displaying second contents specified beforehand when a first prescribed selected contents are not recorded on a tape. CONSTITUTION:When the displaying of an absolute time is requested to a displaying part 23a by a displaying contents selecting switch 23b-1, a system controller 16, when said absolute time is recorded in the tape, displays said absolute time identified by a signal processing part 13 at the displaying part 23a, and when the absolute time is not recorded in the tape, the program time identified by the signal processing part 13 is displayed at the displaying part 23a. Thus, even when the displaying of the contents not recorded in the tape is requested, some displaying is executed at the displaying part 23a and the unnatural feeling is deleted.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Applications> The present invention relates to a display method in a DAT device, and particularly to a display method when requested content is not recorded on a tape.

<Prior art> In DAT, audio data (
PCM data) along with subcodes, ATF numbers, etc. should be recorded. Then, in the subcode area of each track (as shown in Figure 3), the track number (program number), SHU-ID indicating the beginning of the track, and the elapsed time from the beginning of the tape (absolute time), elapsed time of the song (program time), etc. are recorded.
These subcode information are displayed as appropriate during playback.

For example, as shown in FIG.
is constantly displayed, and the absolute time (A-TI) selected by switch operation is displayed in the second area IB.
ME), program time (P-TIME), and tape running count (C0UNTER) are displayed as appropriate. In addition, Fig. 4 (al is an example of absolute time display,
FIG. 4(b) is an example of program time display, FIG. 4(C) is an example of running count display, and IC is a level display area.

<Problems to be Solved by the Invention> By the way, absolute time may not be recorded depending on the tape. In such a case, when absolute time display is requested, conventionally nothing is displayed in the second display area IB as shown in FIG. 4 (dl).

The same applies when no program time is recorded, and generally nothing is displayed when a request is made to display content that is not recorded on the tape.

However, it feels unnatural to leave it dark without displaying anything, and it is unreasonable not to display anything even though there is a display section.

In light of the above, an object of the present invention is to provide a display method in a DAT device that displays other predetermined content when a request is made to display content that is not recorded on a tape. .

Means for Solving the Problems> FIG. 1 is a block diagram of a DAT device to which the present invention can be applied.

13 is a signal processing unit, 16 is a system controller, 23
23a is the operation panel, 23a is the display section, 23b is the key part, 23
b-1 is a display content selection key.

Function> When it is requested by the display content selection switch 23b-1 to display the absolute time (A-TIME) on the display section 23a, the system controller 16 (il if the absolute time is recorded on the tape) displays the absolute time identified by the signal processing unit 13 on the display unit 23a, and (II) if the absolute time is not recorded on the tape, displays the program time similarly identified by the signal processing unit 13. is displayed on the display section 23a, and (if the Iω program time is not also recorded on the tape, for example, a bar (--: --knee-1 is displayed on the display section 23a).

<Embodiment> FIG. 1 is a block diagram of a DAT device to which the present invention can be applied.

11a and llb are first and second recording/reproducing heads, 13 is a signal processing section, 14 is an analog audio circuit, 15 is a speaker,
16 is a system controller; 17 is a loading/unloading device for loading/unloading a cassette into a predetermined position and loading/unloading a tape onto/from a drum;
18 is a loading/unloading mechanism; 19 is a tape running control unit that causes the tape to run at an appropriate predetermined speed (play speed, fast forward speed, review speed, cue speed, etc.); 20 is a tape running mechanism; 2
1 is a drum rotation servo unit that rotates the drum at a predetermined speed; 22 is a drum rotation mechanism such as a drum morph; 2
3 is an operation panel.

The operation panel 23 has a display section 23a and a key section 23b,
A portion of the key is provided with various keys, including a display content selection key 23b-1 for selecting content to be displayed on the round bar display section.

The signal processing unit 13 controls the recording/reproducing head l in the playback mode.
The audio data read from the tape by la and llb is stored in the built-in RAM, and the audio data is subjected to error detection, correction, and other processing.
+14 and after DA conversion, audio is output from the speaker 15, and furthermore, the star 1-ID, absolute time, program time, program number, etc. included in the subcode are identified and input to the system controller 16. ing.

The system controller 16 has a microcomputer configuration, including a processor (CPU) 16a, a program memory (
ROM), RAM 16c, etc.

FIG. 2 is a flowchart of the process of the present invention, and the overall operation of FIG. 1 will be explained below according to this flowchart.

For example, during play, a predetermined display content is selected by operating the display content selection key 23b-1 (step 101).

Once the display content is selected, the system controller h-16
The processor 16a checks whether the selected display content is "absolute time" (step 102), and if it is absolute time, it writes absolute time to the tape.
Is the time recorded? In other words, the signal processing unit 13
Check whether the absolute time (A-TIME) is being sent from the computer (step 103), and if so, display the absolute time (A-TIME) on the display section as shown in FIG. 4 (al) (step 104). .

However, if the absolute time is not recorded on the tape in the judgment process of step 103, the program check is performed in step 103 to check whether the program time is recorded on the tape, or in other words, whether the program time is being sent from the signal processing section 13. 105), if it has been sent, the program time (P-TIME) in Figure 4 (bl
The message is displayed on the display section as shown in step 106), and if it has not been sent, other content, such as the bar shown below, is displayed on the display section (step 07).

On the other hand, if it is determined in step 102 that the displayed content is not absolute time, check whether the displayed content is "program time" (step 108), and if it is program time, check whether the gorogram time is recorded on the tape, in other words, the signal Check whether the program time is being sent from the processing unit 13 (step 1.09).
, if it has been sent, the corresponding program time (P-TIM
E) is displayed on the display section as shown in FIG. 4 (bl).

However, if the program time is not recorded on the tape in the judgment process of step 109, the step is checked to see if the absolute time is recorded on the tape, or in other words, whether the absolute time is being sent from the signal processing section 13. 111), if the absolute time (A-TIME) has been sent,
Step 112
), if it has not been sent, other content, such as the bar shown below, is displayed on the display section (step 113).

Incidentally, if the displayed content is not the program time in the progressive 108, the requested content is displayed (step 114).

Although it has been described above that a bar is displayed when neither absolute time nor program time is recorded, another display, such as a running count display, may be used.

Further, although the case where the present invention is applied to an absolute time display and a program time display has been described, the present invention is not limited to these displays, but can also be applied to, for example, a remaining time display, etc.

<Effects of the Invention> According to the present invention, contents not recorded on tape (
If a request is made to display content (content that the system does not know), the configuration is configured to display another predetermined content, so some kind of display (including bar display) will be displayed, resulting in an error. It doesn't feel natural, yet it's reasonable.
